MACHINE'FOR BEAoaNG AND HAMMERING-EATHER.

SPECIFICATION forming part of Letters Patent No. 359,893, dated March22, 1887.

applicati@ mea .my 24, 18st.

To all whom, it may concern: l

Be it known that I, ANTON SCHMIEDL, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented a certain new and useful Machine for Beadingand Haulmering Leather, and I do hereby declare the following to be afull, clear, and exact description of the invention, reference being hadto the accompanying drawings, which form part of this specilication.

My invention has for its object to provide a machine for beadingshoeuppers or similar leather-work in which the stitched scallops on theedge of leather or equivalent material are beaded and hammered.

My invention consists in the peculiar construction and combinations ofparts, hereinafter fully described and claimed.

In the accompanying drawings, Figure lA is a front elevation of machine,partly broken away. Fig. 2 is a plan View, partly broken away. Fig. 3 isan end elevation. Fig. 4is a vertical longitudinal section ofbeading-bar and finger-plates. Fig. 5 is a plan of parts shown in Fig.4.

This machine comprises several parts,which Y I shall now describe.

E is a clamp or pushing on device, comprising a central rigid tongue,E', and two levers, e e', pivoted on said tongue at e?. Said levers c' eare curved reversely, as shown, and bear with a yielding pressureagainst the 'tongue E', being forced apart at their opposite ends bysprings e3 e3. The tongue E is a prolongation or extension of or isattached by means of an intermediate arm, e5, to a bar, F, which restson the bed-piece G below the top or cloth plate, g, of the latter. Saidbar has liberty of lengthwise movement in a longitudinal slot, h, in aslide-bar, H. Said slide-bar H rests on the bed-piece Gin guides orgrooves in the latter.

I and I are cams on a shaft, I2, below the bars'F and H. The bar F has adepending finger, f, which bears against the cam I, and the bar H has anger, h2, which bears against the cam I, so that when the shaft I2 isrevolved and the cams bear against said fingers thebars F and Hwill bemoved longitudinally outward Serial No. 208,926. (No model.)

erably of spring-steel and being connected by rivets or screws 7d* k3,which pass through a longitudinal slot, k, in the bar K.

k is a rib or tongue between the plates K2 K3 and fastened to both, saidrib tting in the slot k in the bar K', and k2 is a spiral spring,forming an elastic connection between the end of rib la and the opposingend of slot k.

The plates K2 K3 may be recip'rocated longitudinally on the bar K',their movement in one direction being eected or assisted by the pull ofthe spring k2, and their movement in the opposite direction, or in bothdirections, being produced by the bar H, a curved extension, H', of thelatter carrying a pin or stud, h', which enters asocket, k, on the underside of plate K3. rlhe bar K, carrying plates K'z K3, may be turned upor thrown back on its hinge, and disengagement will then be effectedbetween bar H and plate K3. W'hen said bar and plate are in engagement,the positions are as shown in Figs. 2 and 3, and when shaft I2 isrotated the clamp E and plates K2 K3 will reciprocate simultaneously inopposite directions.

The fabric to be beaded is drawn over the finger-plates K2 K", the bar Kbeing first turned up for that purpose and then turned down intohorizontal position, and the shaft I2 caused to rotate. The bars F and Hreciprocate and the clamp E and finger-plates Kl K3 move simultaneouslytoward and then simultaneously apart from each other, the effect ormotion being very similar to that of the thumb and ingers of the humanhand in drawing on or fitting the end of a glove-linger on anotherfinger or thumb.

Normally the outer ends of the plates K2 K3 are in contact with ortouching each other. To cause them to open or spread as they move ICO ;tionary while the machine is in operation, the

finger-plates K2 K3 reciprocating as described,

the fingerf and cam I being omitted.

Preferably the inner sides or opposing faces of the levers e' e aretransversely ribbed or 5 corrugated to produce roughened surfaces orribs, which will act more effectively than plain or smooth surfaces.

I willnow describe the appliances by which the hammering is done.

:o L is avibrating arm secu red to a rock-shaft,

Z, and receiving motion through a connectingrod, Z', having a strap, t2,which encircles an eccentric on shaft l2, so that when said shaft l2rotates, the arm L will vibrate in a 5 vertical plane. Said arm carriesat its outer extremity a hammer, M, of which m is the head and m theshank. This shank is pivoted at m2 in a forked extension, L', of the armL, and has an elastic connection in the form o of a spring, m3, whichlatter is attached at its ends to said shank and arm, respectively.

N is a pad, composed of a cushion, n, of felt, leather, rubber, or otherproper material, fitted in a frame, N', which is secured to the 5 cloth-plate g, the latter being fastened by screws to the bed-piece G.

Vhen the arm L vibrates, the hammer M strikes on the cushion or onfabric placed on the latter. The blow of the hammer is not a n meredownward stroke, but one having a rubbing action, as, owing to thepivotal connection at m2, the hammer-head slides forwardly when it meetswith resistance beneath. So, too, the hammer as it ascends rubs thefabric 5 beneath, as the pull of the spring ma causes said hammer toswing backward] y on its pivot. The action or motion of the hammer istherefore peculiar, being a descending striking and forward rubbingmotion and a backward rub-l n bing motion in ascending. Io ad]- ustablylimit the motion of the hammer, an adjustable stop in the form of ascrew, P, fitted in the extension L', is employed, the rear end of theshank m' abutting against or meeting the lower end of said screw atevery stroke of the hammer. To brace the cloth-plate there is providedan arm, Q, secured at g on one of the standards, Z2, in which therock-shaft L has its bearings.' Said arm extends forwardly, as shown,and carries a bracket-plate, Q', which is L-shaped in cross-section andbears on the top of and against the edge of the cloth-plate g. Saidbracket-plate has a lining of leather or equivalentmaterial, to formacushion for the clothplate and deaden the sound made by the hammer.

R is a pulley on shaft l2, receiving a belt by means of which said shaftis rotated, thereby communicating the required power and motions to theheader and hammer.

O The operation is substantially as follows: 7

The scallops, having been firstv nicked, are turned either by hand or bythe aid of a turning-iron and slipped on the finger-plates K2 K3, thelatter being then brought into a horizontal position by turning down thebar K', which was previously raised or thrown back. The shaft is thenrotated and the beading formed by the conjoint action of said plates orfingers K2 K3 and the clamp E or tongue Eand levers e e'. The scallops,after being moved by hand from the beader, pass successively over thepad N and are acted on by the hammer, the latter acting simultaneouslywith the beader, so that while one scallop is being beaded anotherpreviously beaded is being hammered. It is not, of course, until afterthe first scallop has been beaded that thchammer acts on the work, andwhile the last scallop is being hammered there is no work on the beader.

The advantages of the construction herein described are as follows: Thebeading operation is very effective and rapid, the operation being inimitation of hand-work, but more swift, uniform, and effectual. Thehammering is done by machinery and simultaneously with the beading, thusdispensing with the separate operation of manual hammering heretoforepracticed. The spring k2 not only serves to assist the spring i', butalso holds the plates K2 K2 snugly on the bar K', preventing looseaction or lost motion.

What I claim as my invention is l. The beading clamp or devicecomprising the tongue E and levers e' e,with springs e3 e2,substantially as shown and described.
